При запуске новых программ и игр или после их обновления, а иногда — при доступе к новым функциям ранее использовавшейся программы, некоторые пользователи могут получать уведомления вида «Брандмауэр защитника Windows заблокировал некоторые функции этого приложения» или «Брандмауэр Windows заблокировал некоторые функция приложения во всех общественных и частных сетях».
В этой инструкции подробно о том, почему появляется такое сообщение и что делать, если вы с ним столкнулись в Windows 11 или Windows 10.
Почему появляется уведомление
При использовании параметров по умолчанию, встроенный брандмауэр Windows (Windows Firewall) разрешает большинство исходящих подключений и блокирует входящие, не соответствующие ни одному из имеющихся правил.
Если новое запускаемое приложение «слушает» какой-либо сетевой порт, оно также блокируется по умолчанию.
В случаях автоматической блокировки новых или обновленных приложений вы получаете уведомление или «Брандмауэр Windows заблокировал некоторые функция приложения во всех общественных и частных сетях» либо «Брандмауэр Windows заблокировал некоторые функция приложения во всех общественных и частных сетях» и можете предпринять те или иные действия.
Варианты действий
В зависимости от конкретного сценария появления уведомления о блокировке со стороны брандмауэра защитника Windows вы можете выполнить различные действия.
Разрешение сетевых функций приложения
Базовый вариант, при условии, что вы доверяете приложению и ему требуются функции доступа к сети и получения входящих соединений, просто нажмите кнопку «Разрешить», выбрав соответствующие сетевые профили, в частности — тот, который является активным в вашей сети (про сетевые профили и переключение между ними — в отдельной инструкции).
Разрешение приложению доступа в Брандмауэре Windows требует наличия прав администратора в системе.
Также вы можете разрешить доступ приложения к сети в Брандмауэре Windows вручную несколькими способами, например, в окне «Безопасность Windows»:
- Откройте окно «Безопасность Windows», перейдите в «Брандмауэр и безопасность сети», нажмите по ссылке «Разрешить работу с приложениями через брандмауэр». Если она не активна, это может говорить о том, что на компьютере имеется сторонний антивирус с функциями защиты в сети или сторонний файрволл.
- Нажмите кнопку «Изменить параметры» и включите доступ приложения к сети в Публичной и/или Частной сети, примените изменения.
В списке будет представлены только те приложения, для которых имеются предустановленные правила либо происходило автоматическое срабатывание запроса брандмауэра Windows. Для разрешения другого приложения, нажмите кнопку «Разрешить другое приложение» внизу окна.
Ещё один путь попасть в настройку разрешённых приложений: нажать клавиши Win+R на клавиатуре, ввести firewall.cpl и нажать Enter, выбрать пункт «Разрешение взаимодействия с приложением или компонентом в брандмауэре Защитника Windows» в меню слева.
Отключение уведомлений
При желании вы можете отключить уведомления брандмауэра Windows 11/10 при блокировке приложений.
Для отключения уведомлений:
- Откройте окно «Безопасность Windows», перейдите в «Брандмауэр и безопасность сети», нажмите по ссылке «Параметры уведомлений брандмауэра».
- Отключите ненужные уведомления: либо все, либо только уведомления о блокировке действий.
- Также вы можете настроить уведомления в Win+R — firewall.cpl — «Изменение параметров уведомлений».
Учитывайте, что при этом доступ каких-то приложений к сетевым функциям может быть ограничен, при этом вы узнаете об этом только по поведению соответствующего приложения.
Отключение брандмауэра
Существует возможность полного отключения брандмауэра защитника Windows. Я не рекомендую этого делать, но при необходимости это возможно. Для отключения доступны несколько способов. Один из самых быстрых — «Безопасность Windows».
- В окне «Безопасность Windows» откройте раздел «Брандмауэр и безопасность сети», нажмите по текущему (активному) профилю сети.
- Отключите Брандмауэр Microsoft Defender в соответствующем разделе:
Другие способы отключения описаны в детальных инструкциях для Windows 11 и Windows 10.
Некоторые дополнительные нюансы, касающиеся рассмотренной темы и которые могут оказаться полезными:
- Если даже после разрешения какого-либо приложения в брандмауэре для него продолжают появляться уведомления о блокировке некоторых функций, попробуйте выполнить следующую команду в командной строке от имени администратора, вручную задав имя правила и указав путь к исполняемому файлу программы:
netsh advfirewall firewall add rule name="Имя правила" dir=in action=allow program="путь_к_программе" edge=yes enable=yes profile=domain,private,public
- При необходимости вы можете сбросить все настройка брандмауэра на настройки по умолчанию, если предполагается, что проблемы возникли из-за их изменения. Для этого нажмите клавиши Win+R на клавиатуре, введите firewall.cpl и нажмите Enter, затем используйте опцию «Восстановить значения по умолчанию». Также опция сброса политик брандмауэра доступна в разделе «Дополнительные параметры» в пункте меню «Действие».
- В ситуации, когда запросы появляются при входе в Windows от неизвестных вам программ, рекомендую проверить систему на наличие вирусов и других угроз, например, с помощью KVRT.
- Если вы случайно заблокировали приложение в запросе брандмауэра и не знаете, что это за приложение (чтобы внести изменения в правилах брандмауэра), откройте «Просмотр событий» и изучите события в разделе «Журналы приложений и служб» — «Microsoft» — «Windows» — «Windows Firewall With Advanced Security» — «Firewall», произошедшие в момент блокировки.
Если у вас остаются вопросы на тему блокировки действий приложений брандмауэром, вы можете задать их в комментариях ниже — я постараюсь предложить решение.
Windows Defender Firewall plays a vital role in protecting your malicious threats by blocking network access for certain apps and programs. If it finds an app suspicious, it would pop up a dialogue box saying “Windows Defender Firewall has blocked some features of this app”.
What if you repeatedly get this notification for most apps that need an internet connection such as Spotify, Chrome, Opera, or any other app? More specifically what if you try to access some features of an application and bump into “Windows Defender Firewall Has Blocked Some Features Of This App”?
Needn’t jitter! Here are ways in which you can fix the issue.
5 Ways To fix “Windows Defender Firewall Has Blocked Some Features Of This App”
1. Run Windows Firewall Troubleshooter
Much before you try out any of the other fixes, you can run the Windows Firewall Troubleshooter. In many cases, users were able to fix the issue by doing the same. Here are the steps to run the troubleshooter –
- Open Settings by pressing Windows + I.
- Click on System.
- From the right, click on Troubleshoot.
- Click on Other troubleshooters.
- Under Others click on Run next to Incoming Connections.
2. Turn Off Windows Firewall
Before you follow the steps mentioned below, we recommend that you download a trusted third-party Antivirus tool as an additional security measure. We have also discussed one such tool in the next workaround. Meanwhile, to disable the Windows Firewall, here are the steps –
- Open the Run dialog box by pressing Windows + R.
- Type Control and press Enter.
- In the search box of the Control Panel, type Firewall and click on Windows Defender Firewall.
- Click on Turn Windows Defender Firewall on or off
- Under both Private network settings and Public network settings, click on the Turn off Windows Firewall (not recommended) radio button.
3. Scan For Malware
Up until this point, if you are still getting the error, you can bring a third-party antivirus into force as the application you are running could be malware. T9 Antivirus is one such antivirus that can help you detect and remove malware in real-time.
Why Can I Trust T9 Antivirus?
T9 Antivirus comes with “Web Protection” and “Firewall” Protection modules. The “Web protection” module will prevent you from accessing websites that might be infected with malware. On the other hand, the “Firewall Protection” feature will analyze incoming traffic and provide a robust defense against vulnerabilities. Also, it will also allow you to control internet access for installed applications. To know more about T9 Antivirus, you can check out this post.
4. Allow the App Through Windows Defender Firewall
Even if after passing through a third-party Antivirus, the application has come clean, you can try manually allowing the app through the Windows Defender Firewall. Here are the steps to add the program to the Windows Firewall whitelist –
- Open the Run dialog box like the steps shown above.
- Open Control Panel and head to System and Security.
- On the right, under Windows Defender Firewall, click on Allow an app through Windows Firewall.

That’s because the error “Windows Defender Firewall has blocked some features of this app” often appears when your Windows is connected to a public network. So, if you have marked your office or home Wi-Fi network as public, change it to private using these steps –
- Open Settings as shown above.
- From the left, click on Network & internet
- Click on Wi-Fi.
- Click on your Wi-Fi network.
- Under the Network profile type, click on the Private network radio button.
Wrapping Up
Quite naturally, if you installed an app, you would want to extract its complete potential. But, there are times when Windows Security might stop you from using an application completely and partially. In that case, the first thing you can do is to ascertain that the application you are using is genuine for which you can enforce a second line of defense in the form of a third-party Antivirus tool. And, if you are sure that the application is genuine, you can try out the steps mentioned in this post.
When launching a program on a Windows computer, you may encounter the “Windows Defender Firewall has blocked some features of this app” security alert. While you can click “Allow access” to proceed, it’s not doing anything or going back in circles, leading to frustration.
But there are fixes we can provide for this issue. Just stay tuned.
What’s Causing This Windows Defender Firewall Has Blocked Some Features of This App?
Windows Defender Firewall monitors applications attempting to connect to the Internet and blocks them by default the first time they try. It displays a security alert, and you can click “Allow access” if you trust the app or “Cancel” to keep it blocked.
The “Windows Defender Firewall has blocked some features of this app” notification appears when an application attempts to access your computer’s network or internet connection without proper permissions—this security measure safeguards against unauthorized access.
However, in some cases, malware operating covertly like servers can trigger similar firewall alerts, indirectly causing notifications to pop up on your system.
If the firewall frequently blocks trusted apps, you may need to investigate for potential issues, such as dubious plugins in your web browser or VPN clients causing alerts.
Here are a few steps to stop your PC’s Windows Firewall security alert message.
Fix: Windows Defender Firewall Blocked A Program

Scan Your System for Malware
Certain malicious software can operate as servers, potentially triggering firewall alerts on your system. If you suspect your computer may be infected, it’s advisable to perform a comprehensive scan using a reputable antivirus program to detect and remove any malware present.
Malware can interfere with your system and cause false security alerts. It’s essential to ensure your system is clean.
- Open Windows Security: Press Win + I, go to “Update & Security,” and click “Windows Security.”

Solved Answer
“Windows Firewall has blocked some features” is an error that may occur on any Windows OS version (10, 8, 8.1, 7, etc.). Windows Firewall[1] is an in-built Microsoft Windows application that filters information coming to the system from the Internet and potentially dangerous applications (PUA).
The “Windows Firewall has blocked some features” error is typically triggered by false Firewall rules or third-party VPNs, such as Hotspot Shield[2], Tunnelbear, VPNFilter[3], VPNTop, AdVPN, and others. In general, Windows Firewall is used for allowing or rejecting the connections under the domain, private, and public levels. The firewall is a basic security measure ensuring a secure connection between the two hosts via IP address, port, or WiFi.
Although the “Windows Firewall has blocked some features” error is not the most common one, people keep reporting in on Microsoft forum from time to time for many years. Although experts agree that the issue is most frequently triggered by a third-party VPN application, which hasn’t been allowed in the Firewall, some people claim that this issue may be caused by virus infection. Therefore, we would strongly recommend scanning the machine with a reputable AV engine in the first place.
